How to replace the Renault Scenic's control arm

Today we will explain how to replace the control arm on a Renault Scenic model 3 vehicle. To perform the replacement of the arm, we need to remove the bolts on the wheels so that we can remove it and have full access to the suspension system.

Lift the car and place the front part on jack stands. Using a wire brush, brush the fixing nut of the control arm ball joint and spray some penetrating oil. Clean the disc with brake cleaner.

After cleaning the parts, use an 18mm wrench to unscrew the fixing nut of the support joint. Using a ball joint separator, separate the control arm from the support joint.

Use a pry bar to detach the hub carrier from the control arm ball joint. Brush the fixing bolt of the control arm rear bushing and apply penetrating oil. With a 21mm wrench or a socket wrench with a 30 insert, screw in the rear fixing screw of the control arm, then remove it. Use the 21mm wrench to unscrew the bushing nut. Now remove and insert the new control arm. Mount the rear and front bushing screw without tightening it. Mount the hub carrier on the control arm ball joint and lift the arm to the ball joint level using a jack, then tighten the bushing screws.

Use a torque wrench to tighten the bolt and mount the wheels, then lower the vehicle back to the ground.
